Bonjour, Je suis confronté depuis quelques temps à un soucis chez un client. Parfois, j'ai une perte de communication avec ma passerelle SEW (en profinet, DHR41B), ce qui entraine un arrêt machine et qui se reproduit assez fréquemment (4 à 5 fois dans la journée). J'ai pu relevé le tampon diagnostic de l'API. (En PJ) Avez-vous une idée du problème ? Merci d'avance pour vos retours

Hello Pierre; Members on the Siemens forum come from many countries, and a great number of participants do not speak French. To make sure that the maximum number understand the questions asked here, we have decided on a common language for exchanges, English. Here are links to the latest GSDML file for the DHR41B from SEW (verify that this is the GSDML file that you have integrated in the configuratpor) and the DHR41B ,manual: - SEW DHR41B gsdml file: SEW_GSDML_Controller-DHR_V2-25_20131216 - Manual SEW advanced DHR41B for Ethernet/IP, Modbus/TCP^and Profinet IO: https://download.sew-eurodrive.com/download/pdf/16730410.pdf The bestway of finding a fault in the controller operations is to open the diagnostic buffer of your CPU, along with the suggested diagnostic OBs (see the attachment below, from the DHR41b manual). If your program does not use OB86, OB82 and OB122, add them to your S7 program , and load them to the CPU program (you do not need to program anything inside these OBs for the moment). Your diagnostic buffer willl use the interfaces of these OBs to provide better information on the cause of the failures of your Profinet modules. Once your OBs are integrated, you can upload the contents of the diagnostic buffer to a text file (Save AS...button) that you can attach here on the forum so we can examine and help you understand the contents. Section 11.2 suggests program blocks to gauge the status of the DHR41B Fieldbus interface that must be created in MOVITOOLS Studio, along with process data communication blocks that can also help out with diagnostics. Hope this helps, Daniel Chartier |
